Answer 1

Answer:

They must mix

37 pounds of the House Blend

3 pounds of the Kenya Blend.

Step-by-step explanation:

Let 'x' be House coffe and 'y' be Kenya Coffee. Then:

10.50x + 12.80y = 10.67(40)

Also, we knw that:

x + y = 40

Solving the system of equations above, we have that:

x ≈37.0435 ≈ 37 pounds

y ≈2.95652 ≈ 3 pounds

They must mix

37 pounds of the House Blend

3 pounds of the Kenya Blend.
